The Lin syndrome (strangury) recorded in medical texts presents with various symptoms, and the so-called "various types of Lin" cannot be exhaustively listed. If named according to their etiology, such as Lao Lin (fatigue strangury), Jing Lin (fright strangury), Han Lin (cold strangury), Shi Lin (dampness strangury), Feng Lin (wind strangury), Shu Lin (summer-heat strangury), up to Bao Lin (sudden strangury), although there is no fixed consensus, all fall under the causation of the Three Causes (internal, external, and neither internal nor external). One should carefully deduce the treatment based on these causes; no situation is beyond treatment. There is also Zhuan Bao (displacement of the bladder), where the bladder ligaments are twisted and misaligned, causing inability to urinate; its symptoms are distinct and must not fail to be differentiated. However, treating it should also involve promoting diuresis (promoting urination); ancient formulas prescribe taking Shenqi Bawei Wan (Kidney Qi Eight-Ingredient Pill), which contains Fu Ling (Poria) for this reason.

The *Classic* states: "When the Bladder lacks smooth flow, it becomes Long (stagnant urine/retention); when it lacks control, it becomes Yi Ni (involuntary urination)." This is caused by the loss of proper transmission between the Heart and Kidney Qi. Thus, some experience painful, scanty urination with leakage, while others have incontinence without awareness. Furthermore, women during the postpartum period, due to difficult labor, may injure the Bladder, resulting in involuntary urination at any time. Additionally, children may wet the bed due to cold in the bladder, and this condition may persist into adulthood. Each has specific treatments.
